Discharge Monitoring Report-Quality Assurance (DMR-QA) study program participation is mandatory for major and selected minor National Pollutant Discharge Elimination System (NPDES) permit holders in accordance with Clean Water Act Section 308. The DMR-QA study program is designed to evaluate the analytic ability of the laboratories that perform chemical, microbiological and whole effluent toxicity (WET) analyses required in the NPDES permits for reporting results in Discharge Monitoring Reports (DMR). Under DMR-QA, the permit holder is responsible for having their in-house and/or contract laboratories perform proficiency tests and submit results for grading by proficiency test (PT) providers. Graded results are transmitted by either the permittee or PT provider to the appropriate federal or state NPDES regulatory authority. Permit holders are responsible for submitting corrective action reports to the appropriate regulatory authority when results are unsatisfactory.
There is an increase of 1,259 hours in the total estimated respondent burden compared with the ICR currently approved by OMB. This increase in burden hours can be attributed to an increase in discretionary selection of minor permit holders for participation by state coordinators. Labor costs were revised upward due to market changes and inflation. Non-labor costs for obtaining proficiency test samples also increased.
